JOHN P. EVERTZ, OF SAN DIEGO, CALIFORNIA.

HOT-AIR SILK-REELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 691,457, dated January 21, 1902.

Application filed April 26, 1901.

T at whom it may concern.-

Be it known that I, JOHN P. EVERTZ, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Hot-Air Silk-Reelin g Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a silk-reeling machine for reeling from wet cocoons direct to the spool, through which course the strand is packed and rounded and the silk thread comes off from the spool or drum dry and free; and my invention embraces, among other things, certain devices for passing the strand or strands for the wet cocoons to the final spools or drums, the heating apparatus, the treadle operations, and the spooling and winding devices.

My invention is intended for a domestic or foot-driving machine, but may be used as a power or factory machine.

In the accompanyingdrawings, illustrating my invention, Figure 1 is an elevation of a side view of the machine; Fig. 2, a top plan View; Fig. 3, a front View; Fig. 4, a cross View in the line m an of Fig. 2, the seat and treadles being omitted; Fig. 5, a transverse section through y y of Fig. 4; Fig. 6, a perspective view of the strand in its course; Fig. 7, a detail of winding apparatus; Fig. 8, a perspective, detached, of the devices for lifting the treadles.

In my invention 1 dispense with the usual winding from the cocoons first upon reels, then unreeling from its reels, then making the silk into skeins, and then sending the skeins to market or to factories to be twisted, and I thus save great loss and liability of tangling from frequent handling of skeins in removing from reels, tying into hanks or skeins, boxing or baling, transmission to the factory, and subsequent handling at the factory and preparing at that place of the skeins before spooling. V

A indicates a table for the machine, but adapted for factory use; B, a top box with chambers, and C a removable front portion of Serial No. 5 7,5 77. (No model.)

the box, which is provided with latches o for releasing or securing such front part.

1 2 3 4 1 2 3 4 are small holesin the front and in the top ofeach chamber, which are provided to support reels, hereinafter named, these reels being free to turn on an axis. To avoid complication, only one such reel is illustrated in its own chamber 2.

Above boX B is a pulley support or frame 5, supporting three pulleys 6 7 8, and also above this frame are a spool-spindle 9 and its spool 10. This spindle carries a pulley 11, resting on the endless cord D, which connects the pulleys 6 7 S 14. A side pulley 12, over which this same cord passes entirely around, is supported on a short shaft or pin. A double pulley 14 14: is secured to a crank-shaft 15, which is operated by the treadles. A basin for water and for the silk cocoons is indicated at 16. It is located directly over the hot chamber 17. This hot-air chamber -or tube 17 is provided with tubes 18(four be- 19 is for shutting off hot air when desired,

and it extends into the tube 17 and has a tube 20 within it. This tube 2Q is for receiving hot air when the lamp is not employed for such purpose, a'valve or opening coinciding in these tubes 19 and 20. The turning a little on this exterior tube serves to open or close at will both of these valve-openings. At the end of tube 19 is provided a notched disk 19*, by which it may be properly turned for closing or opening, a pin limiting this movement. 21 is a stool or seat for the operator. Small treadles 22, with brace-rods 22, are for the purpose of pushing the cranks of the crankshaft 15. Upon pushing fully down a long treadle and then pressing its small treadle down the crank moves over the dead-center. These devices are specially important in this machine, tending to insure practically a uniform movement in efiecting the compactness and rounding of the twisted strands at the points between the pulleys 29 29,as shown. A stove or coal-oil lamp is indicated at 23.

In chamber 2 is illustrated one of the reels. (See Fig. 4.) The long treadles 25 are provided with connecting rods attached to a crank-shaft 15. A key or cam 27 serves for lowering intoaction or for raising out of action by turning it partly around the spoolspindle 9 and its spool 10. When raised, its pulley 11 nolonger rests on the cord D and ceases to be driven by the friction of the cord.

It will be seen that the long treadles 25 are for the foot-power, and the small treadles 22, resting on them,are for pushing on the cranks. Each small treadle has a link 22, (see Fig. 8,) connecting to a bent or angle lever e, the upper end of which connects by a rodfto the crank-shaft. Similar connections from the similar small treadle I have for distinction lettered as 22', e, and f.

A most essential part of my machine and. operations relates to the dry hot reeling from the Wet cocoons direct the twisted and dried strands or thread formed from the filaments from such cocoons andv wound on a spool or drum, as above indicated. Astrand (marked S) of severalsay four or fivefilaments is passed first over the two guide-pulleys 29 29, (see Fig. 4,) supported one above the other at proper distance from each other above the basin, the filaments passing once over around these pulleys, as shown. Then this strand is twisted some thirty (30) or forty (40) times upon itself mid way between these guidepulleys. In the drawings to avoid confusion only a few of these twists are shown. The twisting of the silk is of very great importance, especially between the pulleys 29 29. When properly done, the compactness and roundness of the strand is effected. After leaving the pulleys 29 the strand having passed through its holesay 2-it passes one or two times around the swivel 24:, as shown, thence to the top hole 2 in the upper part of the chamber, and thence once around a transverse bar 30, which in its traverse 0r swing is operated by its link 31, reciprocated by pulley 12. (See Fig. 1.)

It will of course be understood that in a factory-machine, wherein steam or other power shall be employed, the lamp or stove and the treadles would be omitted. As a domestic or foot-operated machine it can be run with one, two, three, or even more strands, as any person can conveniently handle. As a factorymachine there may be moresay ten-sets of devices running. \Vhen foot-power is used, the tube 20 should be closed at its ends by any means-say corks. In a factory-machine any heating apparatus should be connected with the tube 20.

I claim- 1. In combination,a cocoon pan or holderfor heating water in the same, a pair of rollers serving to guide the strands from the cocoons, a heated closed drying-chamber provided with apertures or holes through which the said strands are led, a reel within said chamber and around and from which the strands pass to said apertures or holes to the outer air, and a spool-winding device, all substantially as set forth.

2. The heating apparatus having in combination, the basin for the cocoons, a hot-air chamber 17, a box provided with a dryingchamber, hot-air-delivering pipes 18 from said hot-air chamber to the drying-chambers of the box, and means provided as set forth forheating said delivering-pipes.

3. A hot-air silkmachine, comprising in combination a heater for heating the wet cocoons,a series of heated drying-chambers each connected by a tube from the heater, means for guiding the strands from the cocoons into said chambers, a spool-winding apparatus, a set of foot-treadles for operating the winding apparatus, and an endless cord D, and system of pulleys connecting the treadles with the winding apparatus, all substantially as set forth.

4. In combination with the heater,the series of heated drying-chambers, the tubes from they heater to said chambers, means for guiding the strands from the cocoons into said chambers, a set of foot-treadles,the set of auxiliary treadles, and the winding apparatus.

5. A hot-air silk-machine, comprising a cocoon-heating pan, guide -pulleys for the strands from the pan, a drying-chamber, a reel in said chamber to dry the strands,.a spool, the spool-spindle 9, and the means described for raising out of action or for lowering into action said spindle.

In testimony whereof I have affixed my signature in presence of two subscribing Witnesses.
